Tower Crane Series
Tower crane is the latest domestic hoisting and transport machinery designed and manufactured by DeYing. using group technology, modular design and finite-element analysis and taking computer design platform for tower crane as the tool.
This crane is a type with cantilever, bogey jib lubbing and upper slewing lifting. All its performance parameters and technical indicators have reached or are superior to the national standard. The maximum working range is 55m; independent freestanding height 45m; adhered freestanding height 160m; rated lifting torque 800kN.m, maximum lifting capacity 6t.
This crane is advanced in parameters, reliable in performances, beautiful in appearance, high in quality, simple in structure and easy in operation. It is equipped with advanced safety devices and is easy for repair and maintenance, safe for use and reasonable in pricing, for which it has become an ideal choice for many construction enterprises.
It can be widely used in large-scale, ultra-high type of civil construction, power plants, bridges, dams and other works.
The crane boom is hinged to a frame on which is mounted a winch operating the boom through a pulley tackle. The fixed pulleys of the boom tackle are mounted on the crane frame and the movable pulleys thereof are linked to the boom head. The boom tackle has auxiliary pulleys mounted on symmetrically positioned brackets pivoted to the crane frame parallel to the boom luffing plane. The rope is reeved so that its parts connecting the movable and fixed pulleys run parallel to the boom luffing plane and the auxiliary pulleys are each connected to the movable pulleys by the same number of rope parts. Another winch mounted on the frame raises and lowers the load. The drums of both winches are kinematically interconnected so that they simultaneously rotate in opposite directions, whereby the boom is elevated while the load is lowered. Thus, the load is moved in a true horizontal path while the reach of the crane boom is varied.
The primary advantage of Topless Crane is that the overall height has been reduced with the crane no longer having a top tower, while the hook height has been maintained. This makes the crane suitable for congested sites as it can easily overfly other cranes on site. Some of the cranes sold to the local market will also be used on sites where space is a problem.
All the components of the range of cranes can be containerised in standard containers. This makes it easier to get it from Europe to South Africa and it also makes it cheaper for the owner of the crane to transport it from site to site.
Bucket wheel stacker reclaimer
The bucket wheel type stacker-reclaimer is the main mechanism designed for high-efficency handling mechanical system at the bulk cargo stowage. The stack capacity rating of stacker-reclaimer designed by DEYING ranges from 1000t/h～7500t/h, applied for handling bulk materials such as coal, iron ore, sand and cement etc. The control, common and PLC control methods can be adopted for the electrial systems according to the customer’s requirement to realize the semi-automatic and full automatic operation of stacker-reclaimer.
